Anatoly Karpov and I donated the prize fund from our 1986 world championship match to the Chernobyl victim relief fund. - Garry Kasparov

The implicit, or even explicit, offer made by authoritarians is stability in exchange for liberty. High oil prices allowed Putin to keep this bargain for a while, aided by an international community that lost interest in promoting liberty as soon as the Berlin Wall fell. Putin was welcomed by the G7 as an equal while destroying democracy and civil society at home. Imagine how difficult it was for us in Russia to attack Putin’s regime as undemocratic while he was being embraced by the leaders of the free world. Even Putin’s invasion of neighboring Georgia in August 2008 resulted in no censure or sanction. He was rewarded by Obama and Hillary Clinton’s reset a few months later, confirming to him that a move into Ukraine would also go unchallenged.

It’s still unfathomable that Russia went from joyously celebrating the end of totalitarianism to electing a KGB lieutenant-colonel in just nine years. Never take your liberty for granted, and be careful whom you vote for because it may be the last election you’ll ever have.

You must also have a sense of when to stop.
